High availability for critical applications
Executive Summary and key Constraints In enterprise, there are applications with specific high availability requirements. Online transaction processing (OLTP) applications are prime examples of this requirement. Deploying high-availability (HA) architectures for these applications across multi-site environments requires balancing data consistency, recovery objectives, and operational complexity while adhering to constraints. This post evaluates architecture options for a write-heavy, mission-critical OLTP application deployed across two on-premise data centers using open-source tools. Current State (Deployment) ...
